An ad set is showing high impressions but low click-through rate across various placements. Which specific Ads Manager report breakdown should be analyzed first to identify which placement is underperforming?

The specific Ads Manager report breakdown that should be analyzed first to identify which placement is underperforming is the 'Placement' breakdown, found under the 'Breakdown' menu in Ads Manager, typically within the 'Delivery' category. Placement refers to the specific locations within Meta's platforms and partner network where an ad can appear, such as Facebook Feed, Instagram Stories, Audience Network, or Messenger Inbox. This breakdown directly segments your ad performance data by each individual placement, providing a granular view of how your ad performs in each distinct location. By applying this breakdown, you can view the impressions and click-through rate (CTR) for each specific placement. Impressions represent the total number of times your ad was displayed. CTR is the percentage of people who saw your ad and clicked on it, calculated as (Clicks / Impressions) 100. Analyzing this breakdown allows you to pinpoint which specific placements are generating a high volume of impressions but yielding a disproportionately low CTR, indicating poor engagement or relevance within that particular placement, such as an ad performing well in the Facebook Feed but showing a significantly lower CTR in the Audience Network despite accumulating many impressions there.
